[0002] In modern manufacturing, sheet metal quality inspection is a crucial process that directly affects the quality and performance of the final product. Currently, sheet metal quality inspection usually involves capturing images of the sheet metal surface and then analyzing and determining whether the sheet metal is qualified. However, this image acquisition and inspection method has certain limitations:

[0003] During image acquisition, the sheet material's conveyance must be temporarily stopped to obtain clear image information. This practice interrupts the production line and reduces production efficiency. To achieve precise stopping during image acquisition and subsequent continued conveyance, the control system must perform complex fixed-point sensing and calculations, which not only increases the complexity of the control system but also makes the production process more difficult to control. The control system must precisely control when to stop and resume sheet material conveyance, which places high demands on real-time monitoring and feedback mechanisms, increasing the difficulty of program control.

DETAILED DESCRIPTION

[0042] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0043] This embodiment provides a sheet material packaging machine with dual-station identification, such as Figures 1 to 13 , including a frame 01, and also including a loading device 02, a weighing device 03, a detection device 04 and a blanking and selecting device 05 all arranged on the frame 01;

[0044] The loading device 02 is used to transfer the sheet material to be processed to the first weighing device 03; the weighing device 03 is used to detect the weight of the sheet material to be processed to determine whether it is the weight of a single sheet material. If it is determined to be the weight of a single sheet material, the sheet material is transferred to the detection device 04;

[0045] The detection device 04 includes a double-station material picking mechanism, a detection mechanism, and a conveying mechanism, all of which are installed on the frame 01. The conveying mechanism is used to convey the sheet material. The detection mechanism includes an upper visual detector and a lower visual detector. Both the upper visual detector and the lower visual detector are line scan cameras.

[0046] The upper visual detector is located above the sheet material, and the lower visual detector is located below the sheet material; the double-station material picking mechanism is used to drive the sheet material to move so that the lower visual detector detects the bottom surface of the sheet material; the conveying mechanism drives the sheet material to move so that the upper visual detector detects the top surface of the sheet material;

[0047] The blanking and sorting device 05 is used to sort the sheets inspected by the inspection device 04 into good or bad products, and to transfer the sheets inspected as good products to the next station.

[0048] Specifically, if Figure 2 As shown, the sheet material operation process of this embodiment is: first place the sheet material to be operated on the loading device 02, and the weighing mechanism moves the sheet material at the loading device 02 to the weighing platform. The purpose of weighing is to determine whether the moved sheet material is one, to prevent the sheet material from sticking due to static electricity and other reasons. After the weighing is qualified, the sheet material is moved to the conveying mechanism of the detection device 04, and the double-station material picking mechanism is cooperated with the upper visual detector and the lower visual detector to perform line scanning on the two surfaces of the sheet material to determine whether the sheet material is qualified, and the detection result is provided to the blanking and sorting device 05. The good and defective products are separated and blanked by the blanking and sorting device 05. The defective products can be manually recycled, and the good products are conveyed to the packaging device for packaging, thereby completing the detection and packaging of the sheet material.

[0049] More specifically, Figures 2 to 5 As shown, the loading device 02 of this embodiment includes two loading stations 11 and a plate limiting mechanism, the loading station 11 is used to place the plate to be processed, the plate limiting mechanism includes an adjustable limiting member and a position adjustment component, the loading station 11 is provided with a plurality of limiting holes 12, the limiting holes 12 are equipped with the adjustable limiting member, the position adjustment component is used to control the position of the adjustable limiting member in the limiting hole 12, the adjustable limiting member is used to limit the position of the plate in the loading station 11; the adjustable limiting member is provided with a blowing hole 13, the blowing hole 13 is connected to the external blowing structure, and the blowing hole 13 is facing the plate.

[0050] Specifically, if Figure 2 As shown, this embodiment has two loading stations 11, and sheet materials can be placed at the two loading stations 11 at the same time. Then, the subsequent stations can continuously take materials from the two loading stations 11. If the subsequent stations are provided with two taking mechanisms for coordinating the taking of materials, it helps to improve the working efficiency.

[0051] Furthermore, the sheet material is limited at the loading station 11 by an adjustable limiter, such as Figure 2 and Figure 3 The adjustable limiter includes a plurality of x limit rods 14 and y limit rods 15, and the position adjustment assembly includes an x ​​position adjustment assembly and a y position adjustment assembly. The loading station 11 is provided with a limit hole 12, and the shape of the limit hole 12 is as follows: Figure 3 , has a certain length, therefore, by adjusting the position of the x limit rod 14 and the y limit rod 15 in the limit hole 12, it can adapt to sheets of different sizes. Optionally, the x limit rod 14 and the y limit rod 15 are both located below the loading station 11, and the x limit rod 14 and the y limit rod 15 are both provided with a limit hole 12 from bottom to top. The x limit rod 14 and the y limit rod 15 are both provided with a blowing hole 13, and the blowing hole 13 is connected to external blowing equipment. During operation, the blowing hole 13 blows air towards the sheet, which can effectively reduce the static electricity generated between the sheets. Then, the x limit rod 14 and the y limit rod 15 can achieve the limiting effect on the sheet, and at the same time, it can also achieve static electricity removal, prevent the sheet from sticking when moving, and ensure that each sheet can undergo quality inspection and other production operations. The adjustable limit parts realize multiple functions, which helps to make the production equipment structure simpler, reduce maintenance costs, and facilitate production control, making it more practical.

[0052] The x position adjustment assembly includes a synchronization unit, a slider 16 and a track 17. The slider 16 is mounted on the track 17. The synchronization unit is used to drive the slider 16 to slide on the track 17. The slider 16 is used to drive the adjustable limiter to move. The x position adjustment assembly also includes a mounting block 18. The adjustable limiter is assembled on the mounting block 18. There are two mounting blocks 18 and they are respectively mounted on different sliders 16. The spacing between the two mounting blocks 18 is adjusted by the synchronization unit to adjust the spacing between the different adjustable limiters. Specifically, Figure 4 As shown, the x-limiting rods 14 are respectively fixed on the mounting blocks 18. This embodiment is described by taking four x-limiting rods 14 as an example. For the convenience of control, two mounting blocks 18 and two rails 17 are provided, and four sliders 16 are provided correspondingly. One mounting block 18 is fixed to two sliders 16, and the sliders 16 are slidably provided on the rails 17. As long as the two sliders 16 are controlled to move closer to or away from each other, the size of the space formed between the x-limiting rods 14 can be adjusted, thereby being suitable for sheet materials of different sizes.

[0053] In this embodiment, the movement of the mounting block 18 is controlled by a synchronization unit. The synchronization unit includes a synchronization belt 19, a first driver (not shown in the drawings), and a synchronization block 110. The first driver is a conventional technology, such as a motor. The mounting block 18 is equipped with the synchronization block 110, and the synchronization block 110 is installed on the synchronization belt 19. The first driver is used to drive the synchronization belt 19 to rotate. The synchronization belt 19 makes the two synchronization blocks 110 move closer to or farther away from each other. Figure 4 and Figure 5 As shown, the synchronous belt 19 is arranged between the two tracks 17, and the synchronous block 110 is also located between the two tracks 17. The two synchronous blocks 110 are respectively installed on the two mounting blocks 18. In addition, the synchronous belt 19 forms a rotating loop, as shown in FIG. Figure 5 It includes a synchronous belt 111 and b synchronous belt 112, wherein one synchronous block 110 is fixed to a synchronous belt 111, and the other synchronous block 110 is fixed to b synchronous belt 112, so the synchronous belt 19 is Figure 5 As shown, the two synchronous blocks 110 rotate clockwise, and the two synchronous blocks 110 will move away from each other under the drive of the synchronous belt 19, then the distance between the two mounting blocks 18 increases, and the distance between the x-limiting rods 14 will also increase. Conversely, if the synchronous belt 19 rotates counterclockwise, the two synchronous blocks 110 will approach each other, the distance between the two mounting blocks 18 will decrease, and the distance between the x-limiting rods 14 will decrease. Therefore, by controlling the rotation of the synchronous belt 19, the size of the spacing between the x-limiting rods 14 can be controlled, and thus it is suitable for sheets of different sizes, with a simple structure and high flexibility.

[0054] Further, such as Figure 3 In this embodiment, the sheet metal is also limited in the y direction by a y-limiting rod 15. The y position adjustment assembly includes a y-track 113 and a y-slider 114. The y-limiting rod 15 is mounted on the y-slider 114. By driving the y-slider 114 on the y-track 113, the y-limiting rod 15 can be controlled to move, thereby cooperating with the x-limiting rod 14 to limit the sheet metal. The drive structure that controls the movement of the y-slider 114 is conventional, such as a servo motor or a pneumatic cylinder.

[0055] Furthermore, the plate limiting mechanism further includes a baffle 115. After the plate is placed on the loading station 11, it abuts against the baffle 115, and the movement of the plate is limited by the baffle 115. Specifically, Figure 3 As shown, the baffle 115 is set at a position opposite to the y-limiting rod 15, and limits the sheet material in the y direction together with the y-limiting rod 15.

[0056] In order to adjust the height of the adjustable limiter inserted into the limit hole 12 to adapt to different heights and quantities of sheets, such as Figure 2 and Figure 3As shown, this embodiment further provides a lifting mechanism. The position adjustment assembly is located below the loading station 11. The lifting mechanism is used to drive the loading station 11 to move up and down to adjust the distance between the loading station 11 and the position adjustment assembly. The lifting mechanism includes a lifting driver 116, a lifting plate 117, and a lifting drive rod 118. The lifting drive rod 118 is connected to the output end of the lifting driver 116. The lifting drive rod 118 is used to drive the loading station 11 to move up and down. Among them, the lifting driver 116 is a prior art, such as a cylinder. Specifically, the position adjustment assembly is installed on the frame 01. The lifting driver 116 drives the loading station 11 to move up and down through the lifting drive rod 118, thereby controlling the length of the adjustable limiter extending out of the limit hole 12, thereby meeting the height requirements of different sheet materials.

[0057] This embodiment is further provided with a brush assembly 119, such as Figure 3 As shown, the brush assembly 119 can be installed on the adjustable limiter and move together with the adjustable limiter. Of course, a structure that drives the brush assembly 119 to move independently can also be set. It is preferred to set the brush assembly 119 on the adjustable limiter, that is, the brush assembly 119 is located on the side of the sheet material and moves with the adjustable limiter. At the loading station, the sheets are in a stacked state. In order to avoid adhesion of the sheets when transferring them, the brush assembly is used to scrape the side of the sheet material when the adjustable limiter limits the sheet material to separate the sheets and avoid adhesion between the sheets. This ensures that a single sheet material can be transferred so that the operation of the next station can proceed normally. The brush assembly 119 includes a brush and a structure for fixing the brush, both of which are prior art, such as fixing the brush to the adjustable limiter by screws, bolts, etc., which will not be described in detail here.

[0058] In order to improve production efficiency, the present embodiment has two loading stations 11, such as Figure 2 As shown, a dual-station drive mechanism 120 is installed on the frame 01. The dual-station drive mechanism 120 drives the two loading stations 11 to move. If two retrieving manipulator structures are set at the next station, while one manipulator structure discharges the material, the other manipulator structure can retrieve the material at the loading station 11, thereby effectively improving production efficiency. The dual-station drive mechanism 120 is a conventional technology, such as a servo motor drive or a screw drive. By driving the loading station 11 to move and coordinate the retrieving action of the next station, fast and efficient loading can be achieved.

[0059] The weighing device 03 of this embodiment is as follows Figure 1 As shown, it includes a weighing transfer mechanism and a weighing platform. The weighing transfer mechanism is used to move the sheet material of the loading device 02 to the weighing platform, and the weighing platform performs weight detection. If the weight is qualified, the weighing transfer mechanism transfers the weighed sheet material to the detection device.

[0060] Specifically, the weighing transfer mechanism is an existing technology, including a weighing drive component and a weighing material picking component. The weighing drive component has structures such as motor drive, cylinder drive, etc. The weighing material picking component adopts a suction cup material picking method, and the weighing drive component drives the weighing material picking component to move, and then picks up materials at two loading stations, and places the obtained sheet materials on the weighing table for weighing. The structure of the weighing table is also existing technology, and is equipped with corresponding weighing sensors and corresponding qualified weight values ​​of the sheet materials. Therefore, after the sheet materials are placed on the weighing table for weight detection, the quantity of the sheet materials can be determined to reduce the occurrence of missed detections.

[0061] The detection device 04 of this embodiment is as follows Figures 6 to 13 As shown, the conveying mechanism 22 is a conventional technology, such as a conveyor belt conveyor. The sheet material is conveyed by the conveying mechanism 22. Since the sheet material moves on the conveying mechanism 22, the lower visual detector 24 may have a problem of limited detection viewing angle. Therefore, when the sheet material moves close to the lower visual detector 24, the double-station material picking mechanism can grab the sheet material and make the sheet material leave the conveying mechanism 22. The double-station material picking mechanism drives the sheet material to move. When the sheet material passes through the lower visual detector 24, a line scan of the bottom surface of the sheet material can be performed during the movement of the sheet material to check whether there is any problem with the bottom surface of the sheet material. After completing the inspection of the lower visual detector 24, the double-station material picking mechanism puts the sheet material back into the conveying mechanism 22, and the conveying mechanism 22 continues to transport the sheet material. When the sheet material passes through the inspection area of ​​the upper visual detector 23, the upper visual detector 23 performs a line scan on the top surface of the sheet material to determine whether there is any problem with the top surface of the sheet material. When both surfaces of the sheet material are inspected, it can be determined whether there is a problem with the sheet material, and then the sheet material can be sorted into good and defective products. In this embodiment, since the visual detector is a line scanning camera, the sheet material does not need to stop at a fixed point when scanning. It is sufficient to move the double-station material picking mechanism and the conveying mechanism 22 at a uniform speed. Therefore, the efficiency of detection can be improved, and there is no need to set a fixed-point detection function. The functional control of the control system can be simpler and more practical.

[0062] like Figure 9 and Figure 10 As shown in FIG. 2 , the positions of the upper visual detector 23 and the lower visual detector 24 of this embodiment are shown. The bottom surface of the sheet is first inspected, and then the sheet is placed back on the conveyor mechanism 22. After inspection by the upper visual detector 23, the sheet can be conveyed to the next station. Specifically, the conveyor mechanism 22 can be composed of two conveyor belts, which are spaced apart to form an inspection passage 25 for the lower visual detector 24. Figure 10As shown, the actual sheet material can also be inspected by the lower visual detector 24 when it moves between the two conveyor belts. However, in order to avoid being blocked by the conveyor belt, this embodiment sets a double-station material picking mechanism. When the sheet material moves close to the inspection aisle 25, the double-station material picking mechanism lifts the sheet material so that the sheet material is at a certain distance from the surface of the conveyor belt. Therefore, the detection angle of the lower visual detector 24 can be increased, and the scanning and detection work can be performed more accurately. Here, the double-station material picking mechanism only needs to lift the sheet material before it enters the inspection channel. No precise sensing data is required, so it does not increase the control difficulty of the control system. After the sheet material has completely passed through the inspection channel, the double-station material picking mechanism places the sheet material on the conveyor mechanism 22, and the conveyor mechanism 22 continues to convey the sheet material. When it passes under the upper visual detector 23, the upper visual detector 23 can scan and detect the upper surface of the sheet material without performing other actions on the sheet material. That is, the sheet material can be inspected on the upper surface while it is moving to the next station, effectively improving the inspection and production work of the sheet material.

[0063] In order to make the detection of the upper visual detector 23 and the lower visual detector 24 more accurate, the detection mechanism of this embodiment further provides an illumination component, such as Figure 9 and Figure 10 As shown, the lighting assembly includes an angle adjustment bracket and a light source 26. The angle adjustment bracket is installed on the frame 01, and the angle adjustment bracket is used to adjust the lighting angle of the light source 26; optionally, the angle adjustment bracket includes a fixing member 27 and an adjusting member 28. The fixing member 27 is installed on the bracket, and the fixing member 27 is provided with an arc hole 29. One end of the adjusting member 28 is fixed to the light source 26, and the other end of the adjusting member 28 is provided with a connecting hole 210. The connecting hole 210 is locked at different positions of the arc hole 29 by screws to change the installation angle between the adjusting member 28 and the fixing member 27.

[0064] Specifically, if Figure 10As shown, both ends of the light source 26 are locked to the adjustment member 28 by screws or other parts, and one end of the fixing member 27 is locked to the frame 01 by screws or other parts. The other end of the fixing member 27 is provided with a docking hole, and the adjusting member 28 is provided with a connecting hole 210. There are two connecting holes 210, one of which is connected to the docking hole by screws or other common parts, and the other connecting hole 210 is connected to the arc hole 29. Therefore, to adjust the angle of the light source 26, it is only necessary to loosen the connection between the other connecting hole 210 and the arc hole 29, rotate the adjusting member 28 to the target position with the docking hole as the center, and then tighten the corresponding position of the connecting hole 210 and the arc hole 29 by screws. The adjusting member 28 drives the light source 26 to rotate, thereby achieving the purpose of angle adjustment.
